This is the eighth in a 13-part series examining key questions as team training camps open. Today’s camp question: Do the Washington Redskins have bigger worries than RG3’s health? Tomorrow’s question: How will Tom Brady get along with his new weapons?

It’s strange to say, but the much scrutinized health of Robert Griffin III is the least of the Redskins’ worries in training camp. Griffin looks on track to be the Week 1 starter after he received medical clearance in his long recovery from reconstructive knee surgery.

The offense will have its dynamic runner and ballhandler, and given RG3 problems with staying healthy last season, the focus will be more on him thriving as an athletic, accurate passer. When you consider the offensive line and the powerful, straight-ahead style of running back Alfred Morris, the Redskins will still have one of the league’s hardest-to-read offenses.

But this is the NFC East, where there is constant change and intense competition. The Redskins (10-6), who won the division championship last year by a game over the New York Giants and by two over the Dallas Cowboys, look a lot like their 2012 version while the Giants and Cowboys make significant personnel and scheme changes.

The fourth-place Philadelphia Eagles had the most sweeping overhaul, with new coach Chip Kelly and a bevy of new defensive starters. And in the league’s most competitive division, they can’t even be ruled out.

The Giants and Cowboys made a lot of small adjustments to help their passing games, two of the league’s best with Eli Manning and Tony Romo. In response to that, the Redskins did not improve their pass defense enough.

The return of top pass rusher Brian Orakpo will help, but the secondary remains a big question mark. The Redskins ranked No. 30 in the league in passing yards allowed last season, and they had to get creative with the 3-4 to create any kind of pass rush.

There is better defensive backfield depth with former Buccaneer E.J. Biggers and rookies Phillip Thomas and David Amerson. But it’s the first team of the backline, led by DeAngelo Hall, that leaves the team vulnerable on the outside.

It’s a good thing Griffin appears to be healthy because the Redskins will have to outscore opponents in what shapes up as a season of shootouts. In addition to facing Eli Manning and Romo twice each, the Redskins have Peyton Manning’s Broncos, Colin Kaepernick’s 49ers and Matt Ryan’s Falcons on the schedule.

There was never really any concern about Mike Shanahan’s offense, whether it's led by a healthy RG3 or his capable, more traditional passing backup, Kirk Cousins. But the Redskins' defensive holes look bigger, especially when they failed to make any big impact moves.
